<P>PROBLEM TO BE SOLVED: To make it possible to significantly reduce electric energy received from system power (commercial power) by efficiently self-consuming generated power. <P>SOLUTION: A domestic total energy system is constructed by combining a photovoltaic power generating system and an accumulator (NAS battery or the like) with a conventional domestic cogeneration system. This makes it possible to absorb increase in electricity generated, a difference between period of time of power generation and period of time of power consumption, and a gap between electricity generated and amount of consumption per hour; and to efficiently self-consume generated power. <P>COPYRIGHT: (C)2007,JPO&INPIT |
